| Abstract: | A method for the HG-AAS determination of microamounts of lead in poly aluminium chloride and aluminium sulfate used as water scavengine agents is presented in this paper. The optimum conditions for the determination and the tolerance of interfering elements were studied. A simple and rapid method is proposed. Under the optimum condition, a linear relationship holds between the absorbaces and concentrations of lead in the range 0 ?0ng ?ml~(-1). A detection limit of 0. 4ng ?ml~(-1) and a recovery between 90%~110% were attained. |
